El Dorado Holdings is one of the major developers that pushed Maricopa.

"There will be a 20-year period from the start to the end of construction. We’ll build 2,000 a year during good times, 750 in slow times, and there could be 2,500 in hot times."
It appears that they are going to turn Benson into Tucson's Maricopa. I'm assuming mostly retirees and Canadian seasonal/snowbirds.
I think this plan is insane but apparently they are going to try.
